JAR-CLOSURE.

SPECIFICATION formingpart of Letters Patent No. 772,038, dated October 11, 1904. Application filed February 10, 1900. Serial No. 4,809. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES H. Hnss, a citizen of the United States, residing at Zanesville, in the county of Muskingum and State of Ohio, have invented a new and useful Jar- Closure, of which the following is a specification. 1

This invention relates to jar-closures; and it has for its object to provide a new and useful device of this character that is exceedingly inexpensive in construction and efiicient in operation.

The invention primarily contemplates a novel form of fastener or fastening-spring having positive and reliable means for securely fastening the cap of the jar in place while at the same time exerting a central uniform pressure on the cap to provide a perfect seal for the closure.

The invention also has in view the provision of an interlocking connection between the fastener and the cap of the jar to not only provide for the even distribution of pressure upon the cap, but also to prevent lateral displacement of the fastener or fastening-spring.

In the accompanying drawings, which form a part of this specification, Figure 1 is a perspective view of the neck of a jar, showing my invention applied thereto. Fig. 2 is a sectional view of the same. Fig. 3 is a perspective view of the spring-fastener. Fig. 4 is a perspective view of the fastener in an inverted position.

In the drawings, the numeral 1 designates the neck of an ordinary jar or bottle, which is provided at its upper end with an exterior peripheral head 2 and an interior recess or seat 3, adapted to receive a flat cap 4. The cap 4 is provided on its under side with projecting portion 5, which extends into the bottle-neck below the plane of the seat 3. The

upper surface'of the cap 4 is provided with a central recess or depression 6.

Arranged over the cap is a fastener 7. The fastener 7 comprises a fiat spring having inturned engaging hooks 8 and 9 to engage with the peripheral bead 2 at the top of the neck. The hook 9 is provided with an outturned tongue extension 10, forming a grasping portion, and the other hook has a concave edge, as clearly illustrated in Figs. 3 and 4. This concave edge, which fits the receptacle, assists in preventing the fastener from moving laterally on the receptacle. The fastener? is also provided at a point intermediate its ends with a crimp 11, forming a projection which engages in the recess 6 of the cap.

In applying the device a rubber gasket or packing 12 is placed upon the seat 3 and the cap placed over the same. The hook 8 is then engaged over the bead 2 and the hook 9 forced over the bead at the diametrically opposite side of the neck. The projection 11 engages in the recess 6, and being forced against the bottomof the same, that being the only point of contact between the two, there will be'a central pressure on the cap, resulting in an equal pressure around the edges thereof upon the rubber gasket 12, making a perfect seal. Furthermore, the projection engaging in the recess prevents all lateral movement of ,the fastener, and therefore prevents the same from slipping from the bottle. It will also be noted that the grasping portion 10 forms a guiding-'fiange for the book 9 when the latter is forced over the head 2. To release the cap, it is only necessary to press the portion 10 upward, whereupon the hook 9 will slip over the bead 2, and the cap may be removed.

Having now fully described the invention, what I claim as new, and desire to secure by Letters Patent, is

In a jar-closure, the combination of a receptacle provided at its upper edge with a projecting rounded bead and having a seat arranged opposite the bead, a cap fitted on the seat and located within the receptacle and provided with a fiat upper face having a central circular concavity and a fastener constructed of a single piece of flat spring metal and extending entirely across the cap and having a central downwardly-bowed spring-bend fitting within the concavity and extending above the upper face of the lid, terminal hooks engaging the rounded bead and curved to conform to the configuration thereof, one of the hooks being provided. at the end with a concavely-curved edge to fit the receptacle, and

the other hook being extended and bent outwardly to form a projecting handle or grip, and straight intermediate connecting portions disposed at opposite sides of the center and located above and spaced from the lid and extending from the spring-bend to the terminal hooks, the latter being adapted to engage the rounded head at any point.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in IQ the presence of two witnesses.

CHARLES H. HESS.
